When using replacement tires with a different size and design it must first be determined that the replacement tire has the basic qualities to satisfactorily replace the Original Equipment (OE) tires.
The recommended tire pressure (s) for such replacement tires will be derived from the load capacity and air pressure of the OE tires. For instance, if the tire placard depicts a recommended tire pressure of 65 psi and that pressure provides 2540# of load capacity the replacement tires recommended tire pressure would be whatever it takes to get 2540# of load capacity from the replacement tires.

Thank you.
K-Z specifies 50psi, the max, and the current tires are rated for 1360lbs each, also the max. By moving to the 1764lb max rated trailer tire, I should be able to use the tire loading tables to find the pressure that yields at least 1360lbs load.

John,
If you are going to match the load carrying characteristics of the 13" tire, why move to the 14"? Why not take advantage of that increased capacity - by using a higher pressure, which improves the reserve capacity?
